FIELD: instrument making.
SUBSTANCE: use: for correction of position of the defect. Invention consists in that position defect correction method includes: generating ultrasonic vibration on the surface of the object of survey to which the conductive strip is connected; recording of F-echo signal and B-echo signal of ultrasonic vibration; detection of pseudodefects by means of conductive strip based on the detected values of F-echo signal and B-echo signal; obtaining position information of pseudodefects; obtaining the difference between the fragments of the position information of pseudodefects based on position information of pseudodefects; and correction of position information of internal defects on the basis of difference.
EFFECT: technical result is upgraded accuracy of determination of the defect position.
